Can NATO documents be co-mingled with US documents as long as they have the same classification level?

NATO documents cannot be co-mingled with US documents even if they share the same classification level due to the distinct regulatory frameworks and handling protocols that govern NATO and US classified materials. Each organization has its own classification guidelines, security measures, and dissemination controls that must be strictly adhered to for safeguarding sensitive information.

NATO's classification system differs from that of the United States, and such co-mingling could lead to potential security breaches or violations of legal obligations. Furthermore, bilateral agreements and international treaties necessitate that classified information, including NATO material, be handled according to the specific protocols established for each entity. Therefore, maintaining clear distinctions between the documentation of each organization is essential for ensuring the integrity and security of sensitive information, thereby justifying the prohibition against co-mingling these documents.
